    摘要： Free-flowing, particulate foam inhibitor concentrates, which suffer no loss of activity in admixture with surfactants or strong alkalis, are prepared by compacting a mixture of from 1 to 20% by weight of the foam inhibitor with 80 to 99% by weight of a water-soluble salt or salt mixture optionally containing blending aids and having a pH value in the form of a 1% aqueous solution of from 6 to 9.5 under elevated pressure and subsequently size-reducing the compactate to an average particle size of from 0.1 to 2 mm. The presssure applied to the mixture should not significantly exceed the pressure limit at which no further compaction occurs. In addition, the particle porosity, as measured by mercury porosimetry, should be below 10%. The foam inhibitors used are preferably paraffin hydrocarbons, organopolysiloxanes and mixtures thereof with finely-divided hydrophobic solids, particularly finely-divided silica.

C. with agitation for a time sufficient to obtain a homogeneous mixture,(b) a water-insoluble wax in a ratio by weight of (a):(b) of from 3:1 to 1:3, and(c) a water-soluble powdered carrier where the components (a) and (b) are present on the carrier in homogeneous distribution, the powdered carrier being present in such an amount that a free-flowing product results.The primary alcohol of component (a) is preferably a Guerbet alcohol of the formula: ##STR1## A natural or synthetic paraffin wax or mixture of waxes with a congealing point in the range of 40.degree. to 120.degree. C. is used preferably as the wax (b). The carrier (c) is a salt that is compatible with the aqueous system, especially an alkali metal salt from the group of the phosphates, the polymeric phosphates, the borates, carbonates, silicates, sulfates or their mixtures, preferably sodium tripolyphosphate. The product is prepared by mixing the liquid alcohol/silicic acid mixture (a) with the wax (b) and the carrier (c) at temperatures above the congealing point of the wax, cooling of the homogeneous mixture to room temperature with continued mixing and crushing into a free-flowing powder. The antifoaming agent is preferably used in washing and cleaning products in amounts from 0.15% to 15% by weight.
